MOUNTING FOR VENTILATING-FLUES.

Application filed December 9, 1912.

To all whom it may concern:

Be it known that I, FREDERICK C. KAsoH, citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Mountings forVentilatingFlues, of which the following is a specification.

This invention has reference to mountings for ventilating lines, and theinvention consists in the construction and combination of partssubstantially as shown and described and particularly pointed out in theclaims.

In the accompanying drawings, Figure 1 is a sectional elevation of theventilator showing the movable part-s open as in use, and Fig. 2 is acorresponding view to Fig. 1 but showing the same closed.

The ventilator as thus shown is planned to have the highest possibleefiiciency compatible with its size, so that a large volume of air maypass through the same when it is fully open and at the same time bepromptly extended and closed in case of fire or excessive temperature inthe flue, and also to have means for purposely opening and closing thesame at will. To these several ends the said device is built with anumber of parts or features peculiar to itself and comprising a suitablyheavy cylindrical body or tube 5 of sheet metal which, in use, sleevesin the permanent pipe or tube with which the ventilator is connected butnot shown herein. The said body tube 1) may have more or less lengthrelatively than that shown herein and becomes the immediate support forthe other parts and which comprise a chamber 0 of cylindrical outline atthe top which is supported from the said body 6 by suitable brackets clof strap metal and having the upper hood h engaged therewith at theirupper ends and the lower hood 7L near their middle while the shield s issecured at its upper edge in the outwardly offset portion of saidbrackets jointly with the upper contracted edge of lower hood h.

Certain details enter into the construc tions and arrangements which itis material to observe. Thus, the so-called draft shield s is like askirting about the body 5 and is held apart therefrom in inclinedposition by the laterally bracing ends 2 of said brackets cl while theupper edge thereof extends above the edge of said body and is engaged at3 on the said brackets and in such rela- Specification of LettersPatent.

tion to said body as to provide a gradually narrowing draft channel orspace for the outside air between said body and shield and which inducesa draft which discharges relatively above said body into the area overthe same and draws the air in the stand pipe upward. This draft is anatural result or consequence of the arrangement of the said parts andan upward travel of the air is thus induced and maintained. The air thusput in motion finds its normal and natural discharge laterally betweenthe two so-called hoods or shields h and h, and where the lower of saidhoods serves really as a shield against air currents or drafts frombeneath and facilitates the escape of the air while the hood it serves alike pur pose of protection, shield or cover from above and against rainand storm conditions.

The brackets (Z are suitably bent at their ends to make the connectionsat 3 and 4; with the said parts, the same bolts or rivets at said pointsof engagement serving to secure the chamber 0 and hood h at 4 andlikewise at 3 as between the hood h and shield 8. These constructionsare mentioned as the present preferred ones but they may be substitutedby equivalent connections, as is obvious. Now, having the said severalparts arranged and supported as shown, a free and 'sufiicientventilating draft is obtained upward through the body 5 when said bodycomes into right working relations with the system beneath, and the.glass cover 9 serves as a sky-light and is suitably secured on the topof chamber wall C. However, provision needs also to be made in all suchventilating systems against fire from within the building so that theventilator shall not become a draft passage which will stimulate fireand thus become a source of danger. To avoid or defeat such possibilityin the present ventilator I employ means to positively close the sameagainst draft the mo ment conditions become threatening or clangerous.Thus, I show three several telescopically arranged and connected ringsor sections 5 of what constitute a complete closure for the ventilatoras seen in Fig. 2 compared with Fig. l, where said sections are open.Two of said sections have inwardly and outwardly projecting flanges 6and 7 respectively at their edges which engage with the other sectionsas shown, and in the case of the upper section with the flange 7 thereonresting upon the inwardly projecting edge 8 of the hood h. The lower ofsaid sections comes into close fitting relations with the upper edge ofthe body 6 and the total elfect of said sections is to close the exitthrough the ventilator when lowered from position Fig. 1 to Fig. 2.

The. means for controlling or handling said sections or rings 5 comprisea cross brace or bar or spider 10 in the lower of said sections whichcarries a central rigid hanger 12 that has a headed projection on itslower end in which is engaged the slotted end of the controlling lever14. The said lever is shown as pivoted at or near its middle upon abracket 15 fixed in the body 5, and a controlling chain or cable 16 isengaged with the otherwise free end of said lever and serves to operatethe same to raise the said closing sections 5. The said sections areexpected to drop by gravity, so that positive means are required to holdthem up and such means are provided in lever 14 and cord 16, and thesaid chain, rope or cable is suitably fastened to effect this result.However, provision needs to be made for fire so that the ventilator willnot wait to be closed by a person but close automatically when theclegree of heat in the flue or passage approaches the danger point. Tothis end I provide the said cord with a fusible connec tion 18 of anywell known composition and which is sufliciently sensitive to heat tomelt and sever said cord at any predetermined temperature. Thus the saidclosure can be controlled by hand and automatically but normally itremains open.

In operation air is entrained into the direct passage through the fluefrom beneath and the top of the mounting being closed the draft orescape is laterally beneath the hood h and where the sections 5 arehoused above and out of the way. To get the desired efl'ect in orthrough the said skirting or shield s the same must be arranged as shownto form a converging air passage upward and so that at the point ofdelivery the said passage will be narrowed as compared with itsentrance, and with the upper edge of the shield at a higher elevationthan the upper edge of the body I).

What I claim is:

1. A mounting for ventilators having a body and an exhaust above thesame and means about the said body to entrain air into the passagethrough said body having inclined shields top and bottom to protect Isaid exhaust and a chamber at its top, in combination with a series ofrings supported in said chamber in telescopic relation and adapted todrop and close said exhaust.

2. A mounting for ventilators having a chamber in its top closed acrossits top and side and an air exhaust opening next beneath said chamber atthe side, in combina tion with a series of telescopically related ringsadapted to drop and close said exhaust, and means to support said ringsin said chamber.

3. A mounting for ventilators closed across its top and having anexhaust for the air about its side, in combination with a series oftelescopically connected rings collapsed in said top above said exhaustand means to raise and lower saidrings consisting of a hanger connectedcentrally with the lower of said rings, a lever engaging said hanger andmeans to control said lever.

4:. A mounting for ventilators, having a chambered top and an exhaust atits side beneath said top, in combination with a series of rings in saidtop slidably related one with the other and adapted to drop and closesaid exhaust.

5. A mounting for ventilators having a chambered top and an exhaust atits side beneath said top, in combination with a series of ringstelescopically related and adapted to drop and close said exhaust, abody on which the lower of said rings is adapted to seat and means onsaid mounting to engage the upper of said rings about its upper edge andsuspend said rings over said body.

6. A mounting for ventilators having a chamber in its upper portionclosed across its top and a side exit for the air beneath said chamber,and a body from which said chamber is supported, in combination with atelescopically constructed closure for said exit suspended from withinsaid chamber and adapted to engage said body, and means to support saidclosure in said chamber comprising a flexible connection havmg a fuslblelink withm the air passage through said body.
